226 THE ENTOMOLOGIST, 
long; the head is large, intensely black and shining; the body 
is cylindrical, of a creamy white colour, including the legs and 
claspers, and of a rough or velvety texture ; on the first segment, 
encircling the upper half, is a black crescentic collar ; there are 
six longitudinal series of short fine bristles, three on either side. 
The larva, soon after emerging, commences making for itself 
a little tubular dwelling, drawing together the edges of the 
grass-blade by spinning about three or four stout cords of silk, 
each cord composed of a great number of strands, which quickly 
contract, causing the edges to draw together and sometimes to 
overlap, forming a compact short tube; generally before spin- 
ning it nibbles off the extreme edge of the blade where the silk 
is afterwards attached to. It feeds upon the blade both above 
and below its abode, devouring so much that frequently only the 
midrib of the blade remains, and the tube only just long enough 
to conceal it; it then shifts its quarters, and prepares a new 
home. It is particularly active ; upon the slightest touch it 
rapidly runs out of its tube, either backwards or forwards, and, 
after remaining for a time until all apparent danger has passed, . 
it retreats into its abode. : 
The subsequent descriptions refer to the same specimen 
through all stages, so that the exact period from one stage to 
another may be given. 
After the first moult, which occurred on July 8th, the larva 
is nearly a quarter of an inch long; the body is cylindrical and 
slender, without markings; the segments are well defined and 
transversely wrinkled; it is clothed with very short and fine 
hairs, most minute, giving the surface a velvety appearance ; 
the colour is of a very pale yellowish green, in certain lights 
appearing of a whitish green; the head is large, elongated, and 
flattened above, black and shining, as also is the collar on first 
segment. 
Second moult on 17th July. It then measures seventeen- 
twentieths of an inch in length; colour very pale green, with a 
fine longitudinal medio-dorsal line of a darker green, and a sub- 
dorsal green line, slightly darker than the ground colour; each 
line is bordered by a paler stripe; the head is black, and 
mottled with pale brownish grey occupying the centre of each 
lobe, and a blotch above the mouth; there are five glistening 
black warts, set on a glazed collar of pale green, encircling the 
upper half of first segment; the central wart is largest; on the 
last segment is an elongated oval black mark narrowed in the 
centre. On July 24th, being thirty days old and still after | 
second moult, it was exactly half an inch long, one-tenth of an 
inch in diameter, and perfectly cylindrical throughout. 
Third moult on July 30th. Seven days after third moult, 
forty-four days old, it measured seven-tenths of an inch long; 
the body of the same shape as previous stage; colour pale
